摘要：

A resonance state situated at 1.8 +/- 0.1 and, most likely, another state positioned at 2.7 +/- 0.1 MeV above the t+n+n decay threshold were observed in the missing mass energy spectrum of the H-5 nucleus produced in the reaction H-3(t,p)H-5. The peak located close to E-5H = 1.8 MeV also was seen in the H-5 spectrum obtained from the energy distributions of 3H nuclei emitted in the reaction H-2(He-6,H-5)He-3. The width (Gamma(obs) less than or equal to 0.5 MeV) obtained for the two 5H resonance states is surprisingly small. A state of H-4 with E-res = 3.3 MeV and gamma(2) = 2.3 MeV was obtained in the reaction H-2(t,p)H-4 from the proton spectrum.
